Correct pressure for clinchers?

[racman]

This may have been covered before, but I didn't see it and I don't want to hijack the "What Wheels" thread, so my question is - what is the optimal pressure to pump clinchers to. I always pump to the maximum recommended on the side wall (Gp4000 is 120psi) due to being a heavier rider.

 

Are their real benefits to this as opposed to 100psi or less? I always thought it would improve puncture resistance and RR although at the expense of comfort and (possibly) handling?

bly by wat op die side wall staan dis daar vir n rede,en ja as jy swaarder is kan jy dit tot sy max psi pomp

racman, same here.  Would rather take the harder ride than possible snake bite punctures (as per Saturday and SCOTTY and JOE LOW!!!)

I do max on rear wheel and about 10psi less on the front.

I use 100 psi when training, max recommended when racing clinchers in dry conditions (which is not often, I mostly race tubbies when it is dry), 80 psi when racing in moderate to hard rain, I seldom race the tubbies when it rains, the clinchers brake better.

I found this site while looking for the difference between clinchers and tubbies (slow learner ):

Near the bottom he gives a table of possible tyre pressures. He recommends, amongst other things, that the front tyre be around 10% lower pressure than the rear as it carries less weight.

I'd never thought about this in any detail and always used to pump front and back to max pressure (130psi). I'm now going to do a bit of experimenting.
